The 20-year-old centre-back was heavily linked with a move to England at the turn of the year, but snubbed the advances of Premier League suitors in favour of regular first-team football in Denmark.
Manchester United were credited with an interest in bringing Okore to Old Trafford, as Sir Alex Ferguson sought to further strengthen his back line, but it was Chelsea who made an official approach for the Danish international's services, though on this occasion they failed to successfully lure him to Stamford Bridge.
"I chose to turn it down (the Chelsea offer) as it did not fit the strategy I have for my future," Okore explained in an interview with TV2 Denmark.
"My biggest wish is to play first team football and that was not something that was on the cards."
Okore is eager to test himself at a higher level, having tasted Champions League football with Nordsjaelland in 2012/13. However, for the time being he is happy to continue learning his trade with the opportunity for regular action, and defended his decision to snub Chelsea.
"Sure, if you are interested in the money, then it would have been the right decision," he reflected, when questioned whether he should have seized the opportunity to move to England.
"But I love to play football and I want to play football on a regular basis, so if I keep on impressing and playing then I am certain I can develop my game so I can play for Chelsea in the future.
"It was difficult turning down Chelsea, but it would also have been difficult turning down Manchester United.
"You have to think about your own future and I am only 20 years old. For me first team football is the priority. In a couple of years we can talk about money, big clubs and regular football there."
